Webb4 The Peter-Weyl Theorem 25 Theorem 4.3. (Peter and Weyl) Let H be a Hilbert space and G a compact group. Let 7f : G ---+ End(H) be a unitary representation.Then H is a direct sum of finite-dimensional irreducible representations. Proof. We first show that if H is nonzero then it has an irreducible finite dimensional invariant subspace. WebbOne thereby obtains the fundamental Weyl chamber t +:= {x ∈ t: α(x) ...

Webb23 feb. 2024 · The main result is the Peter–Weyl theorem, which, together with Schur orthogonality relations, generalizes the construction of Fourier series on S 1. 1 Representations A (Hausdorff) compact group K is unimodular, as the modular function \Delta :K\rightarrow \mathbb {R}_ {+} is a continuous homomorphism. Webb15 juli 2024 · Peter-Weyl theorem states that as a representation of G × G, L 2 ( G) can be decomposed into L 2 ( G) ≅ ⨁ λ ∈ G ^ V λ ⊗ V λ ∗, where G ^ denotes the set of irreducible representations (irreps) of G. Furthermore, for ( g 1, g 2) ∈ G × G and f ∈ L 2 ( G), ( g 1, g 2) acts on f as ( g 1, g 2) ⋅ f ( g) = f ( g 1 − 1 g g 2).
